BD9897FS-E2 is an advanced Power Management IC (PMIC) designed to improve system performance, reduce power consumption, and simplify design process. It is a specialized power management integrated circuit (PMIC) optimized to address the needs of industrial and embedded applications with higher energy efficiency, longer battery life, and reliable system operation.

The BD9897FS-E2 consists of a wide range of power management and peripheral functions in a single chip package. Due to its integrated power switching, it is well suited for applications that require multiple power resources. Additionally, the device provides an adjustable output voltage which can be programmed to operate in a wide range of voltages.

The primary power management functions of the BD9897FS-E2 include voltage supervision, power control, power factor correction, current sensing, and over voltage protection. For example, the power control functions are used to optimize the power conversion process and allow the device to predict and respond to real time power conditions. The power factor correction function allows the device to provide a variable voltage output depending on the input voltage, thus allowing for independent adjustment of the output voltage.

The BD9897FS-E2 further provides a variety of on-chip peripheral functions, such as PWM controllers, temperature sensors, voltage and temperature monitors, digital signal processors, multiplexers, and Analog-to-Digital converters. These functions are designed to enable the implementation of sophisticated system control algorithms such as PID control, digital signal processing (DSP), and system monitoring into small, low-cost applications.

The operating principle of the BD9897FS-E2 consists of the following steps: First, the incoming AC power is converted to a DC bus voltage by a switching converter. The output of the switching converter is then controlled by the power management functions to optimize the power conversion process. The current at the output of the converter is then monitored by the power factor correction and over voltage protection functions, and the voltage is monitored and adjusted by the voltage supervisor. Finally, the output of the power management is converted to a desired voltage level by an adjustable regulator before being supplied to the system.

The BD9897FS-E2 is ideal for a wide range of industrial and embedded applications. It is particularly well suited for applications that require multiple power resources, tight control of the output voltage, and high energy efficiency. Furthermore, the integrated peripheral functions enable the implementation of sophisticated algorithms for remote monitoring and control. The device is also well suited for appliance and automotive applications due to its wide range of operating voltages.
